Physiological Characteristics of Mental Activity of People with Different Individual Typological Properties of Higher Nervous Activity at a Low Rate of Processing Information

N. P. Chernenko-Kuragina


Introduction. The rhythm of modern life raises the problem of improving efficiency, quality and speed of mental activity. The key issue of its solution may be individually selected style and rhythm of mental activity as well as qualitative and professional selection. The purpose of paper is to find the correlation between physiological characteristics of mental activity and individual-typological properties of higher nervous activity at different stages of processing information with the low rate of giving information.

Methods. Functional Mobility of Nervous Processes (FMNP) is determined in 158 men by M.V. Makarenko’s method on “Diagnost-1” computer system. Mental activity is diagnosed during 30 minutes. The rate of giving information is the same for everyone: 70 stimuli per minute.

Results. Productivity index is higher in the subjects with low FMNP than with high one at the low rate of processing information (p<0.05). Correlation analysis confirms this feature (p<0.05). The individual differences of processing information which depend on the dynamic properties of cortical structures, that is the entire working functional system being determined by typological properties, are not found.

Originality. It is confirmed for the first time that there is no correlation between the volume, quality and speed characteristics of mental activity and the individual-typological properties of higher nervous activity at the low rate of processing information.


Conclusion. There is no correlation and reliable difference of average values between the volume, quality and speed characteristics of mental activities in the groups with the different level of FMNP while processing information with the low rate of giving information. Correlation and statistically reliable differences are found in the groups with the high and low level of FMNP according to the productivity index of mental activity. The individuals with the high level of FMNP are characterized with low productivity level. The necessity of the differentiated approach to applying individual-typological properties of higher parts of central nervous system with the aim of assessing and optimizing mental activity is substantiated.
